A small change now amounts to a massive change in the future.

In 2013 people toyed with the idea of small blocks, this has killed Bitcoin core.

In 2018 people toyed with the idea of changing the protocol and allowing laundering operations to flourish, this will kill Bitcoin cash.

Bitcoin still survives in the form of Bitcoin SV, and the amount of growth in the ecosystem is testament to this. It will flourish in the most positive way.
